My 2012 Volkswagen Passat SE 2.5L Won't Start. What Could be the issue?

What is your question?

When Starting my car it starts but immediately turns off. I have recently replaced the battery because it was bad. I tried changing the fuel pump but that did not resolve the issue. When I turn the ignition to on the check engine light, ABS, EPC, Traction Control lights come on. Radio does not turn on when i turn the ignition on I have to manually turn the radio on and off. Before the car went completely out the car would take a few tries to start but eventually would start. All the same lights came on, but all lights would turn off after driving a while. Car would start fine the rest of the day after initial start. Nothing is working to start the car. Jumping the car would work at one point of time. I have had the alternator and starter checked and it came back fine. What could possibly be the issue here?

What makes this problem better or worse?

N/A
